APPARATUS ron THE 'nANUrAc'rUnEor OXYGEN COMPOUNDS or SULFUR.

To all whom it may concem:

Be it known that I, THoMAs ADAM CLAY- TON, a citizen of the Republic of France, and a resident of 4S Rue de la Victoire, Paris France, have invented new and useful improvements in A paratus for the Manufacture of Oxygen ompounds of Sulfur, of which the following is a specification.

My invention relates to an apparatus for the manufacture of oxygen compounds of sulfur, and especially sulfur dioxid mlxed with sulfur trioxid for use in disinfecting or in the destruction of parasites, insects or for other purposes.

My invention more particularly relates to an apparatus in which the air, required for the combustion, .volatilization and oxidation of the sulfur, is forced into the sulfur combustion furnace at two different levels, in such a manner as to perform said operations in two steps: a first supply of air (primary air), provided at the lower part .of the furnace, delivers the amount of air required for the combustion, and volatilization of the sulfur; a second supply of air (secondary air), provided above the first, in a chamber separate from the lower part of the furnace by one or more baffles, delivers the amount of air required for insuring complete oxidation of the sulfur vapors evolved and avoidin sublimation.

y apparatus is provided with any suitable means for directing the primary air toward the hearth or vessel in which burns the sulfur, while the secondary air is directed, by any suitable means, toward the outlet of the apparatus, so that the secondary air current may not interfere with the outflow of the gases carried over by the primary air current, thus avoiding the back flow of the said gases toward the hearth.

The annexed drawings show, by way of example, different forms of the said apparatus:

Fig. 2 is a horizontal section on line 2 2 of Flg. 1 g;

Specification of Letters Patent.

AIn Fi s 1 and 2, the apparatus consists of a cylm r1cal or other metal vessel A, hermetlcally closed by a cover A1. B is the hearth or vessel in which is located the sulfur, C 1s the charging door, and D D1 are baffles in any suitable number. The pipe E, leading 1n air forced by a fan, branches into two plpes E1, E2, of which one E1 terminates slightly above the hearth B to which it dellvers the air necessar to effect combustion of sulfur; the other-pipe. E2 terminates at a higher level, between the baffles D D1 and delivers the supplementary oxygen required for transformin completely the vapors of uncombined sul ur into SO2 and SO. The

pipes E1 and E2l are provided with registers E3 to allow the delivery of air to be so regulated that, on the one hand, the sulfur in the hearth does not burn too intensely, which Would effect a more abundantvaporization of sulfur than is required and occasion a loss by sublimation, and, on the other hand,

that the amount of oxygen passing into the yapparatus through the pipe E2 is sufficient to oxidize completely the uncombined sulfur vapors and entirely vtransform them into sulfur dioxid. Under these conditions, the gaseous mixture which passes out through the outlet tube F is as rich as possible in SO2 and SO3 and should not contain uncombmed sulfur vapors, which may be easily insured by previously taking samples through the cock f.

The primary air current, flowing in through the pipe E1, is directed toward theA hearth by a deflector consistingin a sheet metal J, inclined to an angle of about 45, secured in front of and above the primary air inlet.

A delector G, arranged near the inlet orifice of the pipe E2, has for its object to direct the current of air, forced in through said orifice, toward the outlet of the apparatus and to avoid a back flow., by 'said current of air, of the gases carried over by the primary air current. Said deflector consists (Figs. l and 2) in a parallelepipedic box G, secured against the wall of the vessel A, near and around the inlet orifice of the secondary air current; this box G is open but on one face, z'. e. on the face turned toward the outflow of the apparatus G1 in such manner as not to interfere with the outfiow of the gases carried over by the primary air current; both currents are thus directed in the same sense.

Patented Jan. 4, 1921. Application led April 2, 1920. Serial No. 370,848.

in the modification shown in Fig. 3 and 4, the primary and secondary air are forced into the apparatus through one and the same pipe; the common orifice is divided, by the baille D, into two juxtaposed inlets; the up- 'per part, H2, is designed for the secondary air supply and represents about one third ot the total area of the opening; the lower part H1, representing the two-thirds of the area of said opening, is for the supply of thc primary air current.

Said primar air current, forced in through the ori ce H1, is, as in Figs. 1 and 2, directed toward the yburning sulfur on the hearth B, by means of a deflector plate J, inclined to an angle of about 45 from the bathe D and extending a little beyond the lower edge O the orifice H1.

The delector of the secondary air current consis s in a'curved sheet metal I, secured t0 the baille D in front of the orifice H2 at a certain distance therefrom, and extending to the wall of the vessel A, on either side of said orifice H2; the secondary air current strikes against said deiiector and cannot escape but upward, as shown in l1, so as not to interfere with the outflow of the gases carried over by the rimary air current, of which gases it comp etes the oxidation into SO2 and S03.

in Figs. 5 and 6 is shown another modification, in Which-the rimary air is let intok the apparatus throug a pipe K, extending into the vessel A and through the same, said pipe bein provided with a series of perito-V rations K?, arranged in such a manner as to direct the current of air in a series of streams, inclined to an angle of about 45, toward the hearth B; the secondary air is forced into the vessel A through a pipe L, which may be branched on the pipe this pipe -L extends into and through the vessel A, arallel to the pipe K, between the bafiies D 1; this pipe L is provided with a series of perforations L1, arranged on the part of the pipe turned toward the outlet ofthe apparatus; these perforations mi ht also arranged on the upper part of t e pipe L,

or in a plane inclined on an angle oi about 45 upward.

The perforations K1 and L1 maybe oi variable size, according to their location onI the pipes K and L, in such a manner as to compensate for the loss of pressure.

It is obvious that an other means might be employed for directing the primar4 and ythe secondary air current respective y toward the sulfur in the hearth and toward the outlet of the apparatus.
